Square D FHL36080 - 80 A, 600 V, 3-Pole Circuit Breaker | AmpState

From AmpState, the Square D FHL36080—80 A, 600 V, 3-Pole molded case circuit breaker—delivers dependable branch circuit protection for panelboards and load centers. Designed for residential, commercial, and light industrial environments, this unit combines a compact molded-case design with a thermal-magnetic trip system to provide stable, repeatable protection. The trip mechanism instantly responds to short circuits while also tolerating normal inrush, reducing nuisance trips and safeguarding wiring and connected equipment. Key features that set this breaker apart

• Space-efficient molded-case design: optimizes panel layout, making it easier to fit into crowded electrical enclosures without compromising protection.
• Thermal-magnetic trip unit: delivers reliable overcurrent protection with precise thermal sensing and fast magnetic trip for high-current faults.
• Three-pole configuration at 80 A and 600 V rating: ideal for multi-phase distribution and medium-voltage panels commonly found in commercial spaces.
• OEM compatibility: engineered to work with matching Square D OEM load centers and panelboards for straightforward upgrades and consistent performance.
• Versatile application: well-suited for a range of settings—from home renovations and small commercial offices to light industrial equipment distributions.

Why this matters in real-world use

In a busy electrical panel, precise, dependable protection is crucial. The FHL36080 prevents damage from overcurrent and short circuits while maintaining uninterrupted service for non-faulted circuits. The 3-pole design ensures coordinated protection across three phases, reducing the risk of unbalanced loads and equipment exposure to fault current.
